Hi Rob, thank you for your answer.
Yes i have tried to uncheck sort by State but the result show the item in alphabetic order, so you have to scroll down the entire list to find them between the other item that aren't in the actual selection..
I didn't know pressing the arrow keys it select the next/previous item. It's very useful and achieve a better way to select the item in sequential order using the listbox.
Actually i think there is no better way to do it.
Thank you very much Rob!
